My invention relates to. bundle carrier attachments ror grain bindingmachines.

One of the objects of the-invention is to,

provide a simple, practical and effective device or attachment'of theclass specified.

y Another object of the invention4 is to arrange for the automaticoperation of the bundle carrier so as to automatically throw or 'dumpthe bundles from the machine.

Another object of the invention is to secure eectiveness, simplicity andaccuracy ofoperation.-

Other objects of the inventionwill appear and be pointed outhereinafter. i 1n the accompanying drawings :k Fig. 1 is a longitudinalsection of a, portion of a harvesting or binding machine provided with abundle carrier attachment embodying my invention, said section beingtaken ii@ on line 1-1 in Fig. 2;

' Fig. 2 is a transverse section taken on line 2-2 in Fig. 1; Fig. 3 isa cross section taken on line 3 3 inFigl; Fig. 4 is acrosssectiontakenon line 1 -4 inFig.3;and

i Fig. is a view of a detail of construction. Referring to the drawings,I show a portion of a binding machine involving a bundle hopper 1 havingpackers 2, 2 and a trip finger or member 4. rIAhis 'mechanism is foundin varied use on` certain types of binders and so of itself is not apart of my invention.

The bundle carrier for receiving bundles from the hopper or chute 1 isshown generally at 5 and involves a plurality of rods 6, 6 ar-KV rangedlengthwise of the machine as well shown in Fig. 1 and inposition belowthe end of hopper or chute 1 so as to receive bundles therefrom, asshown in Fig. 2.

1n yaccordance with my invention bundles received by the* bundle carrierwill bepermitted to collect until any Ldesired number, as for examplefour (4) or five (5)', are ac- 45 cumulated and then` theseV bundleswill be automatically dumped or thrown yfrom the provision is made forthe accumulation of 1 ground, or otherwise, as desired.

the driving link 9 will be held aga-inst move-A Iive (5) bundles, andtheautomatic dumping ofthe same, but the mechanism may be modified so thata dierent number of bundles maybe accumulated before automatic dischargeand may also `be modified in other y ways. 'Y

In this arrangement the plurality of bundle carrying rods'6, 6 arrangedside by side `to receiveand hold the bundles are mounted holdingposition, as shown in Fig. 1. in which' positionk they bundles will besustained and.

held during accumulation, and may also be turned or rocked soY as toswing the bundle supporting .or left-hand portions (Fig. 1) downwardlyso as to permit the bundles to slide 0E from said rods 6, 6 and bethrown or dumpedy fromv the machine upon the To accomplishthis swingingmovement Vof the holding or supporting rods 6, 6 to permit holding anddumping, suitable mecha- `nism is `provided automatically operable bythe operating mechanism` of the machine.

' This may consist of a rocker arm 8 mounted on rock shaft 7 and adriving link 9 pivotally" connected witharm 8 and also pivotallyconnected bymeans of a wrist pinat 10 with a casting or bracket 11bolted on a mutilated 8D gear wheel 12, which is provided for .the

greater operation of its periphery with gear teeth 13, but which has aportion 14- which is stripped or devoid of gear teeth. This wheel hasastop finger 15, preferably formed as part of the bracket or casting 11,and this stop finger 15 serves to engage and hold a stoproller 16 on arod 17 which is pivoted at'18 and provided with a retractile spring 19whichftends normallyto hold its'right- A90 hand end (Fig. 1) in up orelevated position which will cause roller 16 to engage stoprv finger 15.yIn this position the wheel12 will be prevented from turning or rotatingand .95 ment even though the weight of bundles on thecarrying rods 6, 6may tendto depress f said'rods 6, 6 and cause arm 8 to push againstdriving link `9 so as to tend to turn wheel 12. Teethl on wheel 12 areadapted to mesh iceV with teeth on a pinion 21 on a shaft 22, which isone of the rotating or driving shafts of the binding machine and isnormally rotated during the operation of the machine` as shown forexample, by the sprocket chain 23 (Fig. 1) driving a shaft 24 which isgear connected b gear wheels 25 and 26 with said shaft 22. T ie teeth ofgear wheel 12 and pinion 21 are normally out of mesh, however, due tothe absence of gear teeth on the section 14 of wheel 12 and hence wheel12 isnormally stationary and is held normally locked in such stationaryposition by rod 17, as previously explained.

Mechanism is provided, however, for permitting or causing wheel12 toturn sufliciently to release supporting or carrying rods 6,r 6

and dropor discharge the bundles, whena f predetermined orsuiiicientnumberof buiiend of the same, referring to Fig.l 1

fdles has been droppedfor discharged out'of said bundle mechanism.'While this mechanismrmay vary it may consist *ofy mechanism associatedwith the bundle tripping or discharging mechanism of the machine,A asfor example, ay link 3() pivotallyl connected at 31 to the swinging arm32 carrying the bundle discharge finger 4, (Fig. 2) said link 30y beingpivotally connected with a rod or arm 33 pivotally mounted on a shaft 34which also carries a ratchet wheel 35 having teeth 36. Crank arm 33carriesa dog 37 controlled by a spring 38 so that dog 37 normallywillengage teeth 36 `anditurn wheel 35 `as said link is `reciprocatedIup and down by the operation of swinging arm 32. In this way each time abundle passes member 4 and drops into the bundle carrier, the link 30will cause arm 33 to be depressed and then to4 rise and thereby causedog 37 .to-turn wheel 35 a fraction or portion of a revolution. Thenumber of teeth 36 on wheel 35 is the number of bundles it is desired tohave the bundle carrier contain before the bundles are automaticallydumped.` In this case five (5) such teeth 36 yare shown, it beingdesired to have live (5) bundles in the carrier before dumping. Thus,the passage o'f each bundle into the bundle carrier will cause wheel '35to turn one-fifth of a revolution and five (5)l bundles will cause suchwheel to turn a complete revolution.

rIhe shaft 34 carrying wheel 35 also carries a disc or wheel 40 andthisin turn carries a tappet roller 41. The latter is adapted to strike theaforesaid'rod 17 each time shaft 34 performs a complete revolution.Hence, when five (5) bundles have passed tothe bundle carrier and wheel35 has been turned a complete revolution, roller 41 will strike andactuate rod 17, depressing the right-hand This will swing the left-handend of rod 17 upwardly, causing roller 16 thereon to rise above the endof stop finger 15 and thereby release finger 15 and wheel 12. Thispermits ytliegound or otherwise, as desired.

wheel 12 to be turned in the direction indicated by the arrow in Fig. 3,due to the Weight of bundles on carrying rods 6, 6 lowering said rodsand permitting rock shaft 7 to turn and cause arm 8 to push linl; 9 andthereby move or turn wheel 12 in the direction indicated. This downwardmovement of rods G, G permits the bundles to slide or roll downwardlyofi" from said rods and thus to be dumped or discharged from the machineonto The downward movement of therods 6, 6 and discharge ofthe bundleswould, however, leave the supporting or holding rods G, 6 in a downwardposition where further operation of f the vmechanism `in the desiredmanner would not be possible were it not that said rods 6, 6 wereautomatically restored to their upper or holding position afterthe'bundles thereon were discharged. This may be accomplished by thegear wheel arrangement previously described, that is, the cooperatingwheels 12 and 21, the former being stripped of teeth for a portion ofits periphery. The operation of these wheels is such that when rod 17 isVswung upwardly so as to release stop finger i5, the wheel 12 will turnfreely 'a sufficient amount to allow the bundle rods G, G to dump ordischarge the bundles, but at this point wheel 12 has turned suiiciently`to bring its teeth 13' into engagement with teeth 20 on pinion 21.Therefore, pinion 21 `will by its rotation.A turn wheel 12 the balanceof a revolution, until teeth 2() again come out of mesh with teeth 13,and at this time the :wheel 12 will'have actuated drivinglinl: 9

suiiciently to swing arm S back to normal position, as shown in Fig. 1and thereby swing rods 6, 6 upwardly to their bundle holding position,as shown in said ligure.

This operation will be repeated automatically from time to time, thedesired number -ineans including bundle carrying roda. said bundlecarrying rods being arranged to receive the bundles and to be operatedby=the bundles so received.`
